Help is very much appreciated!

2. An artist who lived in the Outer Hebrides wished to replenish his larder and paid a visit to the local farmer.
"You have some fine birds there", he said "what do they weigh?"
"Well sir?, and the farmer, "a turkey and a duck together weigh twice as much as a goose. A goose and a chicken together weigh twice as much as a duck. A goose, a duck and a chicken together weigh twice as much as a turkey. And a duck weighs 8 1/2 pounds."
The artist thanked him and went home to work out the weight of the others.
Find the weight of each of the birds.

Thank you.

t + d = 2g
g + c = 2d
g + d + c = 2t
d = 8.5
2g - t = 8.5
g + c = 17
2t = 25.5
t = 12.75
12.75 + 8.5 = 2g
g = 10.625
c = 6.375
